All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The control method of the transmission of the invention is described below with reference to fig. 1 to 3.
The gearbox comprises a plurality of clutch transmission groups connected in series, each clutch transmission group comprises a plurality of clutch transmissions connected in parallel, each clutch transmission comprises a clutch and a speed change mechanism which are in power coupling connection, each speed change mechanism comprises a gear set, the gearbox is provided with a plurality of gears, and each gear is provided with a corresponding clutch engagement state.
It will be appreciated that the gear ratios of the various clutched transmissions within each clutch pack are different, and that by combining different clutch packs, multiple gears with different gear ratios can be achieved. Each clutched transmission includes a clutch and a variator in series, the transmission being operable to transmit power when the clutch is engaged and to be idle when the clutch is disengaged.
Taking fig. 3 as an example, the gearbox comprises a first, a second, a third, a fourth, a fifth, a sixth and a seventh clutched transmission.
The first clutch transmission and the second clutch transmission are connected in parallel to form a first clutch transmission group, the third clutch transmission, the fourth clutch transmission and the fifth clutch transmission are connected in parallel to form a second clutch transmission group, the sixth clutch transmission and the seventh clutch transmission are connected in parallel to form a third clutch transmission group, and the first clutch transmission group, the second clutch transmission group and the third clutch transmission group are connected in series.
TABLE 1
Table 1 shows combinations of gears and gear ratios of the transmission of fig. 3, where (i) to (c) represent the first to seventh clutching transmissions, respectively.
In some embodiments, the gearbox has a plurality of primary gears and a plurality of backup gears, the backup gears being separated from each other by the primary gears.
It will be appreciated that a gearbox of the above type can form a, b, c gears at most, wherein some gears have smaller transmission ratio differences, and that in the actual design process, all gears can be divided into main gears and backup gears, and the backup gears are set with transmission ratio differences smaller than the target value. When the gearbox is working normally, only the gear is shifted between the main gears, and when a fault occurs, the standby gear can be switched in.
The gearbox formed by the 7(2+3+2) clutch transmissions can form 12 gears at most, wherein the transmission ratio difference of partial gears is small, the gearbox can finally form 8 main gears in total from 1 to 8, and 4 standby gears in total from (1) to (4).
As shown in fig. 1, a control method of a transmission according to an embodiment of the present invention includes: step 110-step 130.
in this step, it can be diagnosed which clutch transmission is faulty, and the detection method includes, but is not limited to: gear ratio detection, output rotating speed detection, virtual simulation system synchronous diagnosis and the like.
A clutch transmission failure may be a clutch failure or a transmission failure.
for example, the target gear is 3, and in 3, if the clutch of the faulty clutch transmission is engaged, it indicates that 3 cannot be currently engaged.
In the related art, if a faulty clutch transmission is detected, maintenance can be directly performed, and the effective working time of equipment where the transmission is located is seriously influenced; according to the control method of the gearbox, when the fault clutch transmission is detected, the alternative gear can be selected, the alternative gear can avoid the fault clutch transmission, and the clutch which does not have faults is used, so that the gearbox can continue to work.
It should be noted that the faulty clutch transmission must be disengaged in the alternative gear.
For example, in table 1 above, when the fourth clutch transmission is a failure clutch transmission, the alternative gears cannot be 3, 8, and (4).
The alternative gear can be a main gear, or the alternative gear can also be a standby gear.
In some embodiments, a backup gear is designed, it should be noted that the target gear is usually the main gear, and by using the backup gear as the substitute gear, the difference of the transmission ratio between the substitute gear and the target gear can be effectively reduced compared to directly using other main gears as the substitute gear.
And step 130, controlling the clutch of the corresponding clutch transmission to be engaged according to the alternative gears.
For each alternative gear, there is a corresponding clutch transmission, and the clutch of the clutch transmission corresponding to the alternative gear may be engaged according to the corresponding relationship shown in table 1, for example.
Thus, even if a faulty clutch transmission is present, the gearbox can continue to operate by the above method.
Particularly, for the engineering machinery in the operation machinery, such as a land leveler, a road roller, a paver and a milling machine, the weight is extremely large, the occupied space (road) is large, and even the engineering machinery can often work in a dangerous area.
According to the control method of the gearbox of the embodiment of the invention, in the event of the failure of the individual clutch transmission, the continuous transmission of power can be maintained through gear shifting.
In some embodiments, step 110, determining a faulty clutched transmission through fault diagnostics includes:
collecting angular speeds of the front end and the rear end of the clutch transmission;
and when the difference degree between the ratio of the angular speeds of the front end and the rear end of the clutch transmission and the target transmission ratio (designed transmission ratio) is not less than the target difference degree, determining the clutch transmission as a fault clutch transmission.
It should be noted that each clutch transmission has a target transmission ratio, when the clutch transmission is in normal operation, the ratio of the angular velocity of the front end (input end) of the clutch transmission to the angular velocity of the rear end (output end) of the clutch transmission is substantially equal to the target transmission ratio, and when the difference between the two is not less than the target difference, the clutch transmission can be determined as a faulty clutch transmission, that is, the clutch transmission is determined as a faulty clutch transmission, that is, the faulty clutch transmission is determined
ω1For angular speed, omega, of the front (input) of a clutch transmission2When the above formula is satisfied, the clutch transmission is determined to be a faulty clutch transmission for the angular velocity of the rear end (output end) of the clutch transmission, i is the gear ratio designed for the clutch transmission, and a is the target difference.
The target difference is a preset value, and in some embodiments, a satisfies:
0≤a≤5％，
such as a-3%.
Of course, the comparison may also be made in other forms, including, but not limited to, directly subtracting the actual gear ratio from the target gear ratio, or directly dividing the actual gear ratio by the target gear ratio.
In some embodiments, after determining the faulty clutched transmission through fault diagnosis at step 110, the method further comprises: and outputting first fault prompt information.
The first failure indication information may be in various forms.
First, the first failure prompt message may be represented by an alarm light on the work machine where the transmission is located, or a buzzer on the work machine.
Second, the first failure notification message may be a notification message displayed on a display panel of the work machine on which the transmission is located.
And thirdly, the first fault prompt message can be represented as a prompt message sent to the remote monitoring terminal, and can inform the after-sales maintenance team of the fault message.
In some embodiments, after determining the faulty clutched transmission through fault diagnostics at step 110, the method further comprises: and in the target gear, if the clutch of the fault clutch transmission is disconnected, setting the gear corresponding to the clutch engagement of the fault clutch transmission as a forbidden gear.
In other words, when a certain clutch transmission has a fault, all gears corresponding to the clutch engagement of the faulty clutch transmission are automatically disabled, so that the situation that the driver is engaged in the gear which cannot normally work in the subsequent working process is avoided, and the safety is improved.
Taking the gearbox shown in table 1 as an example, gear 2, (2) gear 6 and gear 7 are automatically disabled when the third clutch transmission is disabled.
In some embodiments, step 120, determining the alternate gear comprises: step 121 and step 122.
Step 121, determining a gear corresponding to the disconnection of a clutch of the failure clutch transmission as a candidate gear;
taking the transmission shown in table 1 as an example, when the third clutch transmission is failed, the candidate gears are (1) gear, 1 gear, 3 gear, 4 gear, (3) gear, 5 gear, (4) gear, and 8 gear.
By first determining candidate gears, it is possible to help locate the alternate gears quickly.
And step 122, determining an alternative gear from the candidate gears.
In the case where the candidate shift ranges are determined, the alternative shift ranges are selected from the candidate shift ranges, and power output can be ensured.
In some embodiments, step 122, determining an alternate gear from the candidate gears includes: and taking the candidate gear which is closest to the transmission ratio of the target gear as the alternative gear.
In this way, the power output can be made as much as the operator expects when using the alternate gear.
Taking the transmission shown in table 1 as an example, the target gear is 6 th gear, and when the third clutch transmission is failed, the candidate gears are (1) th gear, 1 st gear, 3 rd gear, 4 th gear, (3) th gear, 5 th gear, (4) th gear and 8 th gear; if the gear ratio of the target gear is 1.20, the alternate gear is determined to be 7.
In other embodiments, step 122, determining an alternate gear from the candidate gears includes: based on the target operating conditions, an alternate gear is determined from the candidate gears.
In other words, the alternative gears are selected from the candidate gears by taking the current working condition as the main reference condition.
Taking the transmission shown in table 1 as an example, for example, it is determined that a steep hill needs to be climbed currently based on signals detected by sensors of the engineering vehicle, the target gear is gear 2, and when the 1 st clutch transmission fails, the candidate gears are (1) gear, gear 2, gear 3, (3) gear, gear 6 and gear (4); the alternative gear is gear (1).
In some embodiments, after controlling the clutch of the corresponding clutch transmission to be engaged according to the alternative gear in step 130, the method further includes: and outputting second fault prompt information.
Thus, even if the transmission is currently in use, the operator is alerted that the transmission is malfunctioning and needs to be serviced as quickly as possible.
The second failure notice information may be in various forms.
First, the second failure prompt message may be represented by an alarm light on the work machine where the transmission is located, or a buzzer on the work machine.
Second, the second failure notification message may be a notification message displayed on a display panel of the work machine on which the transmission is located.
And thirdly, the second fault prompt message can be represented as a prompt message sent to the remote monitoring terminal, and can inform the after-sales maintenance team of the fault message.
